Title: Improvements in or relating to metallic cartridge belts
IPC: F42B39/08
Filed: 1936-05-13
Abstract: 473,906. Machine-gun cartridge belts. VICKERS - ARMSTRONGS. Ltd., and HIGSON, P. R. May 13, 1936, No. 13594. [Class 92 (ii)] Relates to metallic cartridge belts of the kind comprising a number of resilient sheetmetal links which enclose more than half the peripheral surface of each cartridge, the links being hingedly connected together by means other than the cartridges themselves. According to the invention, the rear end 3 of each link 1 is flared outwardly to constitute a lead for the insertion of either a rimmed or rimless cartridge, and to permit of the feeding of the cartridge through the link and into the gun barrel chamber. The link shown has a bentover portion or lip 5 adapted to be supported by a projection 8 of the gun. This lip has a curved part 6 which engages with the neck of a cartridge 2 to locate the latter within the link. A further cartridge locating means consists of an inwardly depressed portion or dimple 4 which engages with the rear face of the cartridge. The links have loop portions 10 on either side for receiving the hinge pins, and downwardly projecting resilient edges 11 which grip the cartridges. Alternatively, the cartridges are gripped by means of separate springs.

Title: Improvements in or relating to electric motor control systems

Filed: 1947-05-23
Abstract: 657,479. Control of D.C. motors. IGRANIC ELECTRIC CO., Ltd. May 23, 1947, No. 13901. Convention date, July 20, 1945. [Class 38 (iii) ] A series hoist motor is disconnected from its source at an upper limit of travel, and, at the same time, the motor armature and field winding are connected in a closed loop and in reversed relation for dynamic braking, a master controller supplies power to the closed loop for reverse motor operation for resetting the limit mechanism and means under the control of the master controller establish an armature shunt for the motor and maintains said shunt pending both resetting of the limit mechanism and given adjustment of the master controller subsequent to establishment of said armature shunt. The connections shown in Fig. 2 relate to the last hoisting position of the master controller, the armature a being connected in series with the field winding f, the armature resistors being short-circuited, and the armature circuit completed through limit switches LS<SP>1</SP>, LS<SP>2</SP>. When the limit switch trips, switches LS<SP>1</SP>, LS<SP>2</SP>, open and switches LS<SP>3</SP>, LS<SP>4</SP>, close to establish the braking-circuit of Fig. 3, wherein resistor R<SP>8</SP> is shunted across the armature and field windings, the field winding being reversed. If the limit switches should fail to reset after the motor is reversed to drive away from the limit position, runaway conditions are prevented by the arrangement of Fig. 4 wherein an additional resistor R<SP>9</SP> is shunted across the armature, a relay IC which is responsive to the back electromotive force of the motor is effective to short-circuit resistors R<SP>2</SP>, R<SP>6</SP>, and a resistor R<SP>7</SP> is included in circuit. The values of the resistors R<SP>7</SP>, R<SP>8</SP> and R<SP>9</SP>, are so chosen that the motor speed is restricted to a safe value in the event of overhauling operation. When the limit switches reset the conditions illustrated in Fig. 5 are obtained, the motor being connected as a shunt machine. The resistor R<SP>9</SP> is removed upon movement of the muster controller from the first lowering position, the relay IC is de-energized, and resistor R<SP>4</SP> is included in circuit. The switch AS which connects the resistor R<SP>9</SP> across the motor armature is closed only in the first lowering position of the muster controller, and means are provided for delaying the response of the switch upon return of the controller from the later lowering positions, so as to allow the motor to decelerate.

Title: Improvements in or relating to methods of uniting metal articles by fusion and resulting products such as electric contact assemblies
IPC: H01H11/04
Filed: 1933-05-13
Abstract: 415,221. Brazing electric contacts &c. LAISE, C. A., Tenafly, New Jersey, U.S.A. May 13, 1933, No. 13974. Convention date, March 25. [Classes 83 (ii) and 83 (iv).] In brazing interengaging male and female members, such as electric contacts, the side faces of one or both of the members is or are provided with depressions so as to form capillary passages into which brazing material, placed at the end faces of the members, seeps when melted. One of the members is formed with a shank which is a press fit in the depression in the other member. The members may be of circular, hexagonal, square &c. section. Electric contacts of refractory metal such as tungsten or molybdenum or their alloys, or of precious metals such as platinum or iridium or other alloys are thus brazed on to their base metal supports. The contact 3 may be formed with a fluted shank 5, assembled as a force fit in a recessed support 2 containing a wafer 8 of brazing material such as copper. The parts may be placed in trays of nickel &c. and heated in a hydrogen atmosphere in a furnace to the melting point of the brazing material. Such an assembly may consist of a contact brazed into a threaded stud or into a sheet metal arm. In other forms, the support may have the fluted shank and the contact the recess, or the recess may be fluted instead of the shank, or both may be fluted. In a further form, Fig. 7, the part 3 may have a hollow shank 9, externally and preferably also internally fluted, co-operating with an annular groove 10 in the part 2, the projection 11, if desired, being also fluted. Brazing material 8 is inserted in the recesses. In order to economize in refractory metal or alloy, a base metal piece 22, Fig. 9, with two fluted shanks 21, 23 may be brazed respectively into the contact 19 and support 25. In a further form, Fig. 11, a facing 32 of refractory metal or alloy &c. is first brazed at 37 to a base metal part 33 provided with a plain or fluted shank which is then brazed into a fluted recess in the carrier 36. In this case the brazing material at 37 should have a higher melting point than the brazing material 31 in the recess 35. The brazing material may be applied to the end face of the male member instead of being separately placed in the recess. The refractory or precious metal contact may be made by heading or punching at a red heat in moulds or dies so as to form a rivet with a fluted or plain shank or a contact with a recess.
